Even the great adventurers and the various inventions of those days do not find wisdom. The invention of fire with flint was a big deal. Overturning mountains was a massive task. Cutting channels in rocks was not easy. They used their eyesight to find precious metals. They even tried to figure out the sources of the rivers. They were looking for hidden items by bringing light to them. These were the adventurers and discoverers of 2,500 years ago. They wanted to know about things and how they worked. Yet they never found wisdom.
